Antiviral, antibiotics and decongestants in wastewater treatment plants and receiving rivers in the Thames catchment

A.C. Singer, Järhult, R. Grabic, G.A. Khan, R.H. Lindberg, G. Fedorova, J. Fick, M.J. Bowes, B. Olsen & H. Söderström
This dataset contains the concentration of eleven antibiotics (trimethoprim, oxytetracycline, ciprofloxacin, azithromycin, cefotaxime, doxycycline, sulfamethoxazole, erythromycin, clarithromycin, ofloxacin, norfloxacin), three decongestants (naphazoline, oxymetazoline, xylometazoline) and the antiviral drug oseltamivir's active metabolite, oseltamivir carboxylate, measured at 21 locations within the River Thames catchment in England. The measurements were taken weekly during November 2009, once in March 2010 and once in May 2011, with the aim to quantify pharmaceutical usage during the influenza pandemic of 2009 and...

Data from: Flowering time QTL in natural populations of Arabidopsis thaliana and implications for their adaptive value

Emily L. Dittmar, Christopher G. Oakley, Jon Ågren & Douglas W. Schemske
The genetic basis of phenotypic traits is of great interest to evolutionary biologists, but their contribution to adaptation in nature is often unknown. To determine the genetic architecture of flowering time in ecologically relevant conditions, we used a recombinant inbred line population created from two locally adapted populations of Arabidopsis thaliana from Sweden and Italy. Using these RILs, we identified flowering time QTL in growth chambers that mimicked the natural temperature and photoperiod variation across...

Data from: Reassessment of the non-titanosaurian somphospondylan Wintonotitan wattsi (Dinosauria: Sauropoda: Titanosauriformes) from the mid-Cretaceous Winton Formation, Queensland, Australia

Stephen F. Poropat, Philip D. Mannion, Paul Upchurch, Scott A. Hocknull, Benjamin P. Kear & David A. Elliott
Wintonotitan wattsi, a Cretaceous titanosauriform sauropod from central Queensland, Australia, is redescribed following a full revision of its osteology. The holotype specimen, a partial postcranial skeleton derived from the lower Upper Cretaceous Winton Formation, comprises axial and appendicular elements. Wintonotitan has been commonly resolved as a non-titanosaurian somphospondylan titanosauriform since its description, in contrast to its more derived contemporary Diamantinasaurus matildae. We provide a detailed redescription, taking this opportunity to correct four misinterpretations made in...

Data from: Ontogenetic changes in genetic variances of age-dependent plasticity along a latitudinal gradient

Viktor Nilsson-Örtman, Bjorn Rogell, Robby Stoks & Frank Johansson
The expression of phenotypic plasticity may differ among life stages of the same organism. Age-dependent plasticity can be important for adaptation to heterogeneous environments, but this has only recently been recognized. Whether age-dependent plasticity is a common outcome of local adaptation and whether populations harbor genetic variation in this respect remains largely unknown. To answer these questions, we estimated levels of additive genetic variation in age-dependent plasticity in six species of damselflies sampled from 18...

Data from: Disentangling the contribution of sexual selection and ecology to the evolution of size dimorphism in pinnipeds

Oliver Krüger, Jochen B. W. Wolf, Rudy M. Jonker, Joseph I. Hoffman & Fritz Trillmich
The positive relationship between sexual size dimorphism (SSD) and harem size across pinnipeds is often cited as a textbook example of sexual selection. It assumes that female aggregation selected for large male size via male-male competition. Yet, it is also conceivable that SSD evolved prior to polygyny due to ecological forces. We analysed eleven life history traits in 35 pinniped species to determine their co-evolutionary dynamics and infer their most likely evolutionary trajectories contrasting these...

Data from: AFLPs and mitochondrial haplotypes reveal local adaptation to extreme thermal environments in a freshwater gastropod

María Quintela, Magnus P. Johansson, Bjarni K. Kristjánsson, Rodolfo Barreiro & Anssi Laurila
The way environmental variation shapes neutral and adaptive genetic variation in natural populations is a key issue in evolutionary biology. Genome scans allow the identification of the genetic basis of local adaptation without previous knowledge of genetic variation or traits under selection. Candidate loci for divergent adaptation are expected to show higher FST than neutral loci influenced solely by random genetic drift, migration and mutation. The comparison of spatial patterns of neutral markers and loci...

Data from: Evolution of differential maternal age effects on male and female offspring development and longevity

Elena C. Berg, Martin I. Lind, Ghazal Alavioon & Alexei A. Maklakov
1. Maternal age effects on life-history traits, including longevity, are widespread and can be seen as a manifestation of ageing. However, little is known about how maternal lifespan may influence the maternal age effect. At a given chronological age, a long-lived parent may be at a younger biological age than a short-lived parent, and thus have a less severe parental age effect. However, earlier work using experimentally evolved short- and long-lived lines did not support...

Data from: Coarse dark patterning functionally constrains adaptive shifts from aposematism to crypsis in strawberry poison frogs

Anna Qvarnström, Andreas Rudh, Torkel Edström, Anders Ödeen, Hanne Løvlie, Birgitta Tullberg & Birgitta S. Tullberg
Ecological specialization often requires tight co-evolution of several traits, which may constrain future evolutionary pathways and make species more prone to extinction. Aposematism and crypsis represent two specialized adaptations to avoid predation. We tested whether the combined effects of color and pattern on prey conspicuousness functionally constrain or facilitate shifts between these two adaptations. We combined data from 17 natural populations of Strawberry poison frogs, Oophaga pumilio with an experimental approach using digitalized images of...

Data from: Sperm variation within a single ejaculate affects offspring development in Atlantic salmon

Simone Immler, Cosima Hotzy, Ghazal Alavioon, Erik Petersson & Göran Arnqvist
It is generally believed that variation in sperm phenotype within a single ejaculate has no consequences for offspring performance, because sperm phenotypes are thought not to reflect sperm genotypes. We show that variation in individual sperm function within an ejaculate affects the performance of the resulting offspring in the Atlantic salmon Salmo salar. We experimentally manipulated the time between sperm activation and fertilization in order to select for sperm cohorts differing in longevity within single...

Data from: There is more to pollinator-mediated selection than pollen limitation

Nina Sletvold & Jon Ågren
Spatial variation in pollinator-mediated selection (Δβpoll) is a major driver of floral diversification, but we lack a quantitative understanding of its link to pollen limitation and net selection on floral traits. For 2-5 years, we quantified Δβpoll on floral traits in two populations each of two orchid species differing in pollen limitation. In both species, spatio-temporal variation in Δβpoll explained much of the variation in net selection. Selection was consistently stronger and the proportion that...

Data from: A recently transferred cluster of bacterial genes in Trichomonas vaginalis –lateral gene transfer and the fate of acquired genes.

Åke Strese, Anders Backlund & Cecilia Alsmark
Background: Lateral Gene Transfer (LGT) has recently gained recognition as an important contributor to some eukaryote proteomes, but the mechanisms of acquisition and fixation in eukaryotic genomes are still uncertain. A previously defined norm for LGTs in microbial eukaryotes states that the majority are genes involved in metabolism, the LGTs are typically localized one by one, surrounded by vertically inherited genes on the chromosome, and phylogenetics shows that a broad collection of bacterial lineages have...

Data from: ‘True’ null allele detection in microsatellite loci: a comparison of methods, assessment of difficulties, and survey of possible improvements

Michał J. Dąbrowski, Susanne Bornelöv, Marcin Kruczyk, Nicholas Baltzer & Jan Komorowski
Null alleles are alleles that for various reasons fail to amplify in a PCR assay. The presence of null alleles in microsatellite data is known to bias the genetic parameter estimates. Thus, efficient detection of null alleles is crucial, but the methods available for indirect null allele detection return inconsistent results. Here, our aim was to compare different methods for null allele detection, to explain their respective performance and to provide improvements. We applied several...

Data from: Multivariate intralocus sexual conflict in seed beetles

David Berger, Elena C. Berg, William Anders Widegren, Göran Arnqvist, Alexei A. Maklakov & William Widegren
Intralocus sexual conflict (IaSC) is pervasive because males and females experience differences in selection but share much of the same genome. Traits with integrated genetic architecture should be reservoirs of sexually antagonistic genetic variation for fitness but explorations of multivariate IaSC are scarce. Previously, we showed that upward artificial selection on male lifespan decreased male fitness but increased female fitness compared with downward selection in the seed beetle Callosobruchus maculatus. Here, we use these selection...

Data from: Sperm competition generates evolution of increased paternal investment in a sex role-reversed seed beetle

Isobel Booksmythe, Karoline Fritzsche & Göran Arnqvist
When males provide females with resources at mating they can become the limiting sex in reproduction, in extreme cases leading to the reversal of typical courtship roles. The evolution of male provisioning is thought to be driven by male reproductive competition and selection for female fecundity enhancement. We used experimental evolution under male- or female-biased sex ratios and limited or unlimited food regimes to investigate the relative roles of these routes to male provisioning in...

Data from: Transcriptome resources for the perennial sunflower Helianthus maximiliani obtained from ecologically divergent populations

Takeshi Kawakami, Brian J. Darby & Mark C. Ungerer
Next generation sequencing (NGS) technologies provide a rapid means to generate genomic resources for species exhibiting interesting ecological and evolutionary variation but for which such resources are scant or nonexistent. In the current report, we utilize 454 pyrosequencing to obtain transcriptome information for multiple individuals and tissue types from geographically disparate and ecologically differentiated populations of the perennial sunflower species Helianthus maximiliani. A total of 850,275 raw reads were obtained averaging 355 bp in length....

Data from: The influence of mitonuclear genetic variation on personality in seed beetles

Hanne Løvlie, Elina Immonen, Emil Gustavsson, Erem Kazancioğlu, Göran Arnqvist & H. Lovlie
There is a growing awareness of the influence of mitochondrial genetic variation on life-history phenotypes, particularly via epistatic interactions with nuclear genes. Owing to their direct effect on traits such as metabolic and growth rates, mitonuclear interactions may also affect variation in behavioural types or personalities (i.e. behavioural variation that is consistent within individuals, but differs among individuals). However, this possibility is largely unexplored. We used mitonuclear introgression lines, where three mitochondrial genomes were introgressed...

Data from: Fine scale genetic correlates to condition and migration in a wild Cervid

Joseph M. Northrup, Aaron B. A. Shafer, , David W. Coltman, George Wittemyer & Charles R. Anderson
The relationship between genetic variation and phenotypic traits is fundamental to the study and management of natural populations. Such relationships often are investigated by assessing correlations between phenotypic traits and heterozygosity or genetic differentiation. Using an extensive data set compiled from free-ranging mule deer (Odocoileus hemionus), we combined genetic and ecological data to (i) examine correlations between genetic differentiation and migration timing, (ii) screen for mitochondrial haplotypes associated with migration timing, and (iii) test whether...

Data from: The role of pleiotropy and linkage in genes affecting a sexual ornament and bone allocation in the chicken

Martin Johnsson, Carl-Johan Rubin, Andrey Höglund, Anna-Stina Sahlqvist, Kenneth B. Jonsson, Susanne Kerje, Olov Ekwall, Olle Kämpe, Leif Andersson, Per Jensen & Dominic Wright
Sexual selection and the ornaments that inform such choices have been extensively studied, particularly from a phenotypic perspective. Although more is being revealed about the genetic architecture of sexual ornaments, much still remains to be discovered. The comb of the chicken is one of the most widely recognized sexual ornaments, which has been shown to be correlated with both fecundity and bone allocation. In this study we use a combination of multiple intercrosses between White...

Data from: Worldwide patterns of ancestry, divergence, and admixture in domesticated cattle

Jared Egan Decker, Stephanie D. McKay, Megan M. Rolf, JaeWoo Kim, Antonio Molina Alcalá, Tad S. Sonstegard, Olivier Hanotte, Anders Götherström, Christopher M. Seabury, Lisa Praharani, Masroor Ellahi Babar, Luciana Correia De Almieda Regitano, Mehmet Ali Yildiz, Michael P. Heaton, Wan-Sheng Liu, Chu-Zhao Lei, James M. Reecy, Muhammad Saif-Ur-Rehman, Robert D. Schnabel & Jeremy F. Taylor
The domestication and development of cattle has considerably impacted human societies, but the histories of cattle breeds have been poorly understood especially for African, Asian, and American breeds. Using genotypes from 43,043 autosomal single nucleotide polymorphism markers scored in 1,543 animals, we evaluate the population structure of 134 domesticated bovid breeds. Regardless of the analytical method or sample subset, the three major groups of Asian indicine, Eurasian taurine, and African taurine were consistently observed. Patterns...

Data from: Evaluating the postcopulatory sexual selection hypothesis for genital evolution reveals evidence for pleiotropic harm exerted by the male genital spines of Drosophila ananassae

Karl Grieshop, Michal Polack & M. Polak
The contemporary explanation for the rapid evolutionary diversification of animal genitalia is that such traits evolve by post-copulatory sexual selection. Here, we test the hypothesis that the male genital spines of Drosophila ananassae play an adaptive role in post-copulatory sexual selection. Whereas previous work on two Drosophila species shows that these spines function in precopulatory sexual selection to initiate genital coupling and promote male competitive copulation success, further research is needed to evaluate the potential...

Data from: PCR-based isolation of multigene families: lessons from the avian MHC class IIB

Reto Burri, Marta Promerová, Julien Goebel & Luca Fumagalli
The amount of sequence data available today highly facilitates the access to genes from many gene families. Primers amplifying the desired genes over a range of species are readily obtained by aligning conserved gene regions, and laborious gene isolation procedures can often be replaced by quicker PCR-based approaches. However, in the case of multigene families, PCR-based approaches bear the often ignored risk of incomplete isolation of family members. This problem is most prominent in gene...

Data from: Proxy comparison in ancient peat sediments: pollen, macrofossil and plant DNA

Laura Parducci, Minna Väliranta, J. Sakari Salonen, Tiina Ronkainen, Irina Matetovici, Sonia L. Fontana, Tiina Eskola, Pertti Sarala & Yoshihisa Suyama
We compared DNA, pollen and macrofossil data obtained from Weichselian interstadial and Holocene (maximum age 8400 cal yr BP) peat sediments from northern Europe and used them to reconstruct contemporary floristic compositions at two sites. The majority of the samples provided plant DNA sequences of good quality with success amplification rates depending on age. DNA and sequencing analysis provided five plant taxa from the older site and nine taxa from the younger site, corresponding to...

Data from: Female responses to experimental removal of sexual selection in Drosophila melanogaster

Paolo Innocenti, Ilona Flis & Edward H. Morrow
Background: Despite the common assumption that multiple mating should in general be favored in males, but not in females, to date there is no consensus on the general impact of multiple mating on female fitness. Notably, very little is known about the genetic and physiological features underlying the female response to sexual selection pressures. By combining an experimental evolution approach with genomic techniques, we investigated the effects of single and multiple matings on female fecundity...

Data from: Between-sex genetic covariance constrains the evolution of sexual dimorphism in Drosophila melanogaster

Fiona C. Ingleby, Paolo Innocenti, Howard D. Rundle & E. H. Morrow
Males and females share much of their genome, and as a result, intralocus sexual conflict is generated when selection on a shared trait differs between the sexes. This conflict can be partially or entirely resolved via the evolution of sex-specific genetic variation that allows each sex to approach, or possibly achieve, its optimum phenotype, thereby generating sexual dimorphism. However, shared genetic variation between the sexes can impose constraints on the independent expression of a shared...

Data from: Short term variation in sperm competition causes sperm mediated epigenetic effects on early offspring performance in the zebrafish

Susanne R. K. Zajitschek, Cosima Hotzy, Felix Zajitschek & Simone Immler
The inheritance of non-genetic factors is increasingly seen to play a major role in ecology and evolution. While the causes and consequences of epigenetic effects transmitted from the mother to the offspring have received ample attention, much less is known about how variation in the condition of the father affects the offspring. Here, we manipulated the intensity of sperm competition experienced by male zebrafish Danio rerio to investigate the potential for sperm-mediated epigenetic effects over...
